What's New in Kilowatt

5.4.0

May 29, 2026

Built for the fastest-charging EVs of 2026—and a few fixes you asked for. • New: the Volvo EX60 (P6, P10, and P12) is ready to add to your garage, with accurate charging curves. • Megawatt charging: set DC charging power up to 1000 kW, plus 900V and 1000V vehicle architectures for the latest platforms. • New charger presets for 400, 500, and 1000 kW fast chargers. • Adding your own car? Battery sizes now go up to 250 kWh, and you can fine-tune capacity in 0.1 kWh steps—so packs like the Kia EV4’s 81.4 kWh fit perfectly. • Choose next year’s model year for cars that haven’t arrived yet. Thanks for all the reviews and suggestions—keep them coming!

Un applicatif très utile !

4 ans déjà que je l’utilise pour calculer mes dépenses d’électricité pour ma VE, et c’est super pratique. Je n’ai pas trouvé ma nouvelle voiture Kia EV4 grande autonomie, j’ai dû la créer moi même. Dommage qu à la création je ne puisse la mettre batterie de 81.4kwh mais 81,5… mes félicitations pour cette application gratet utile

Response from developer

Merci pour votre aimable avis ! J’ai bien noté votre suggestion et je vais me pencher sur la modification de la batterie !

Useful

Very useful app for EV car users. Have been using for more than 6 months and so far very convenient to keep track of monthly bills.

Response from developer

That’s great to hear! Thanks for the review it’s much appreciated

Editing rates

Can’t edit rates. Keyboard appears and screen doesn’t slide up and allow edit of the rate.

Nice, but Some bugs

The calculation for consumption is in metric even if you choose Miles.

Response from developer

Oh no! Good catch, that bug might have slipped in in a recent version then. I’ll have a look at that and hopefully we can fix this soon. Thanks for taking the time to send in your feedback! Update: the latest version of the app should fix this 5.0.2

Perfect

Exactly what I needed to work out how long a charge would take and how much it would cost before starting a charge. You can change the charger/speed and start a timer if needed. Perfect!
Would be five stars if could calculate day/night rates together

Response from developer

Thank you for your kind review, i'll put day night rates on the backlog. No promises but noted at least
